Reliable, cheaper, and modular new scada 1

  1. 1. Reliable, Cheaper, and Modular New SCADA System for Wireless Remote Applications Authors: Presented by Associate Professor Head of Electrical Engineering Department, Faculty of Engineering, Jazan Univ.
  2. 2. What is a SCADA? SCADA (Supervisory Control And Data Acquisition) is a type of industrial control system used to collect data and exercise control from a remote location. In the pipeline industry, SCADA systems are used to collect data from pipeline sensors in real time and display these data to humans (controllers). Also SCADA is a process control system that enables a site operator to monitor and control processes that are distributed among various remote sites. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 2

  6. 6. Advantages of SCADA SystemsThe advantages of the PLC/ DCS SCADA system: The computer can record and store a very large amount of data, The data can be displayed in any way the user requires, Thousands of sensors over a wide area can be connected to the system, The operator can incorporate real data simulations into the system, Many types of data can be collected from the RTU’s, The data can be viewed from anywhere, not just on site. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 6
  7. 7. Problems andDisadvantages Of CurrentSCADA System1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 7
  8. 8. Problems of the current SCADA Systems From the SCADA systems development and production point of view, those systems are: ◦ Very complex, Costly, ◦ Requires developed electronic industry in order to produce sophisticated PLCs and to be competitive with different SCADA producers worldwide. Given the complexity of such a systems, especially highly sophisticated PLCs, they are witnessing common trend of attempting to lower SCADA costs on MTU and RTU side. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 8
  9. 9. Main Disadvantages of PLC-BasedSCADA Systems It has restricted software and hardware, Different operating skills are required, such as system analysts and programmer, With thousands of sensors there is still a lot of wire to deal with, (HPOF) The operator can see only as far as the PLC, PLC SCADA system has complexity of system hardware and dependent modules leads to low reliability. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 9

  11. 11. Proposed System Construction Referring to the architecture of SCADA systems, our proposed SCADA system is consists of three main units; Master Terminal Unit (MTU), Remote Terminal Unit(s) (RTUs), and communication protocol software. ◦ MTU is a client PC (Laptop) with open source SCADA software. ◦ Each RTU is composed of ATMEL microcontroller board and Ethernet controller) serves as system server. ◦ The communication protocol software is open source SCADA software with multiple communication capability. The system is attached to an emulator board with analog and digital input and output capability. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 11
  12. 12. Master Terminal Unit (MTU) The MTU itself often consists of two separate subsystems: ◦ A workstation which processes all the information and where the system operator can monitor and control the system. ◦ A communication controller, which takes over the burden of real-time, low-level communication processing and network management, relieving the workstation for other tasks. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 12
  13. 13. HUMAN MACHINE INTERFACE (HMI) HMI is software used to monitor and control the whole system. HMI is the means by which the user (operator) interacts with the SCADA system. The HMI allows the operator to view virtually all system alerts, warnings, and functions as well as change set points, analyze, archive or present data trends. A good and effective SCADA HMI design makes the interaction with the SCADA through the HMI seem natural to the operator, or in other words, clear and easy to understand, with no need for explanation. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 13
  14. 14. PROPOSED SCADA MTU AND HMI The MTU is a client PC (Laptop) with open source SCADA software. It should be noted that many RTU’s could be handled by MTU, while two RTU’s only are implemented in our proposal as an example. The implemented human machine interface (HMI) software is a graphical user interface (GUI) one with an easy way to design, change, depict, and modify any of the system variables. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 14
  15. 15. Remote Terminal Units (RTU) One or more field data gathering and control units or remotes (also called remote stations, remote terminal units, or RTUs). An RTU provides intelligent I/O collection and processing, such as reading inputs from switches, sensors, and transmitters, then arranging the representative data into a format that the SCADA system can understand. RTU also converts output values provided by the SCADA system from their digital form into that which can be understood by field-controllable devices such as discrete (relay) and analog outputs (current or voltage). 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 15

  17. 17. PROPOSED SCADA SYSTEM RTUEach of RTU is composed of microcontroller Ethernet units (ATMEL microcontroller board and Ethernet controller) serves as system server. The microcontroller board features as: ◦ High Performance, Low Power AVR, 8-Bit Microcontroller with the following capabilities:  32 x 8 General Purpose Working Registers  Up to 20 MIPS Throughput at 20 MHz  32 Kbytes program memory, 1 Kbytes EEPROM, 2 Kbytes Internal SRAM  Programming Lock for Software Security  Two 8-bit Timer/Counters, one 16-bit Timer/Counter  Six PWM Channels  6-channel 10-bit ADC. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 17

  19. 19. COMMUNICATION BETWEEN MTU & RTU’S The communication between MTU and RTU of the system may be wired or wireless, via local LAN or via the internet. ◦ The first method for private data transmission includes wire lines or buried cable and modems, and is usually limited to low bandwidth. ◦ The second method to consider is wireless transmission and includes Spread Spectrum, Microwave or VHF/UHF radios, (good for up to 30 miles). ◦ If you need a 24-hour permanent connection for analog data transmission between two or more locations, the Private Leased Line (PLL) should be considered. The Digital Data Service (DDS) with the Digital Subscriber Lines (DSL) and Integrated Service Digital Network (ISDN) should be considered for high speed/low error rate applications. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 19
  20. 20. COMMUNICATION PROTOCOLS A protocol is a set of rules that governs how digital messages are exchanged. In the early years of SCADA systems, few if any communications standards existed, hence individual SCADA equipment vendors each created their own exclusive proprietary protocols.  Some Communication ProtocolsMODBUS Ethernet/IP (applied in our Design)PROFIBUS ControlNetInfiNET HARTUCA FieldbusDistributed Network Protocol Utility Comm. Architecture (UCA)(DNP)Inter-Control Center Comm. Telecontrol Application ServiceProtocol (ICCP) Element (TASE) 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 20
  21. 21. WHY MODBUS PROTOCOL? MODBUS is an open standard Master/Slave application protocol that can be used on several different physical Layers. MODBUS is an application-layer messaging protocol. It provides client/server communication between devices connected on different types of buses or networks. MODBUS -TCP means that the MODBUS protocol is used on top of Ethernet-TCP/IP. MODBUS -TCP is an open Industrial Ethernet network. 1/17/2013 Reliable, Cheaper, and Modular New SCADA Dr. Mohamed Zahran 21
